Answer:

Explanation:

Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).

Use the exponential term in the Arrhenius equation to explain how temperature affects reaction rate.
WINSTONCH [101]

The Arrhenius equation describes the relation between the rate of reaction and temperature for many physical and chemical reactions

It is an expression that provides a relationship between the rate constant (of a chemical reaction), the absolute temperature.

The Arrhenius equation,

k = zpe^{\frac{- Ea}{RT} }, where

k is the rate constant,

z is the collision factor,

p is the steric factor,

Ea is the activation energy,

R = 8.3245 \frac{J}{mol. K} is the ideal gas constant, and,

T is the temperature.

The activation energy by definition, is the minimum energy (or threshold energy) required for two particles of reactants upon collision to form products.

The Arrhenius equation could also be written as:

⇒ k = Ae\frac{-Ea}{RT}, where

⇒ A = zp, the Arrhenius factor.

Taking the neutral logarithm of both parties, we get:

⇒ In k = \frac{-Ea}{RT}\frac{(1)}{(T)} + In A,

Assuming that, A is independent of temperature, when T is increased, the equilibrium constant k will also increase and therefore, the rate of the reaction will also increase.

Complete and balance the molecular equation for the reaction of aqueous sodium carbonate, Na 2 CO 3 , and aqueous nickel(II) chl
pantera1 [17]

Answer:

NiCl2 (aq) + Na2CO3 (aq) ---> NiCO3 (s) + 2NaCl (aq)

Explanation:

Soluble ionic compounds exist as ions in solution.

Na 2CO3, will contain Na2CO3 (aq) --> 2Na ^+ (aq) + CO2 ^-3 (aq)

The same way, a solution of calcium chloride,  

CaCl 2, will contain CaCl2 (aq) --> Ca2^+ (aq) + 2Cl^−  (aq)

Mixing both solution, the calcium cations  

Ca 2^+ , will apir up with the carbonate anions,  CO2^−3 , and form the Insoluble calcium carbonate, CaCO ^3, which precipitates out of solution.

The complete ionic equation, which features all the ions that are present in solution, will be like this

2 Na^+ (aq) + CO2^−3 (aq) + Ca2^+ (aq) + 2Cl^−  (aq) --> CaCO 3 ↓ (s)  + 2Na^+ (aq) + 2Cl^− (aq)

Notice that you have two sodium cations and two chloride anions on the products' side, which is why you have  2NaCl

NiCl2 (aq) + Na2CO3 (aq) ---> NiCO3 (s) + 2NaCl (aq)
